PowerBI Specialist (Contract) | £350-£450 p/day (Outside IR35) | 3 Months (strong possibility of extension) | ASAP - We're hiring on behalf of a fast-growing SaaS company that's looking for an experienced Power BI Specialist to take ownership of their reporting environment. This is a fully remote contract role, starting immediately. The client has a strong BI foundation in place, but they're now looking for someone who can streamline reporting, reduce maintenance, and optimise their use of Power BI at scale. Right now, customer-specific reports are managed individually (e.g. 45+ reports needing updates when a change is made). They want to consolidate, automate, and improve efficiency across their reporting suite. This is not a 'start from scratch' build - instead, you'll be reviewing what's already in place, identifying improvements, and implementing changes to drive
